Guidelines

• Text should be complete, punctuated sentences and ≤ 140 characters.
• Alert messages should be human-readable.
• Alerts should always be visible regardless of where the user is on the page. See 'hidden/visible' interaction below.
• If the message requires additional explanation, use inline links to direct the user to the relevant resource.
• Alerts may be dismissed by the user, but should not disappear on their own.
